(VB.NET UWP/WinRT) FTP through HTTP Tunnel (FTP over HTTP Proxy)Note: This example requires Chilkat v9.5.0.51 or greater. FTP through an HTTP tunnel (via an HTTP proxy server that supports HTTP tunneling).
' This example requires the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. Dim ftp As New Chilkat.Ftp2 ftp.Hostname = "ftp.example.com" ftp.Username = "login" ftp.Password = "password" ' Set the HTTP proxy server properties. ' This is to connect via HTTP/1.1 using CONNECT method ftp.HttpProxyHostname = "192.168.1.127" ftp.HttpProxyPort = 8080 ' If the proxy server requires authentication... ftp.HttpProxyUsername = "myProxyUsername" ftp.HttpProxyPassword = "myProxyPassword" ' FTP over an HTTP proxy requires that FTP Passive mode be used ' for data transfers. It is not possible to use non-passive (active) mode ' for FTP over HTTP. ftp.Passive = True ' Connect and login to the FTP server. Dim success As Boolean = Await ftp.ConnectAsync() If (success <> True) Then Debug.WriteLine(ftp.LastErrorText) Exit Sub End If ' Change to the remote directory where the file will be uploaded. success = Await ftp.ChangeRemoteDirAsync("junk") If (success <> True) Then Debug.WriteLine(ftp.LastErrorText) Exit Sub End If ' Upload a file. Dim localFilename As String = "c:/temp/hamlet.xml" Dim remoteFilename As String = "hamlet.xml" success = Await ftp.PutFileAsync(localFilename,remoteFilename) If (success <> True) Then Debug.WriteLine(ftp.LastErrorText) Exit Sub End If success = Await ftp.DisconnectAsync() Debug.WriteLine("File Uploaded!") |
